The eSoftTools NSF to PST Converter makes converting NSF files to PST files simple and reads Lotus Notes Archive files in Outlook. An NSF Mailbox's data can be retrieved and exported to a variety of file formats, including PST, EMLX, MBOX, and VCF. To ensure that all of your email data is retained during the conversion process, review the contents of your NSF files before converting them to PST files.
